  2. 6. Inverse ration ventilation : experimental studies on pulmonary integrity and gas exchange

    Author : Ulf Ludwigs; Karolinska Institutet; Karolinska Institutet; []
    Keywords : respiration; artificial gas exchange lung function acute respiratory distress syndromeacute lung injury inverse ratio ventilation ventilator induced lung injury intrinsic PEEP lungclearance;

    Abstract : In this thesis, pulmonary and circulatory effects of inverse ratio ventilation (IRV) have been studied experimentally. Comparisons have been made between volume and pressure controlled IRV and conventional ventilation under conditions of equal minute ventilation and end-expiratory alveolar pressure levels. READ MORE

  4. 7. Regional ventilation, pulmonary perfusion and gas exchange in supine and prone positions

    Author : Margareta Mure; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ARDS; ALI; CPAP; Gas exchange; Prone position; Regional ventilation; Regional perfusion; Supine position;

    Abstract : The rationale for treating patients with acute lung injury in the prone position springs from a number of observations. Clinical reports have documented improved oxygenation when patients are turned prone. Regional vascular conductance is higher in dorsal lung regions regardless of posture. READ MORE

  5. 8. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape

    Author : Adrian Reber; Uppsala universitet; []
    Keywords : Medical sciences; Anesthesia: epidural; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Abstract : Induction of general anaesthesia causes a rapid decrease in functional residual capacity, which can promote alveolar collapse (atelectasis) and airway closure in dependent lung regions. Mismatching of ventilation and perfusion (VA/Q) in the lungs is accompanied by impairment of pulmonary gas exchange. READ MORE

  6. 9. Atelectasis and gas exchange impairment after cardiopulmonary bypass : An experimental study

    Author : Lennart Magnusson; Uppsala universitet; []
    Keywords : Medical sciences; Lung: cardiopulmonary bypass; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Abstract : Despite of the improvement in management and equipment for cardiopulmonary bypass (CPB), postoperative pulmonary complications remain a major problem after cardiac surgery. In the present thesis, using a pig model, atelectasis has been tested as a cause of the increase in intrapulmonary shunt commonly seen after CPB. READ MORE
